摘要：
The goals and objectives of the study were to investigate and compare the physiological effects of a heated oxygen-helium mixture (heliox) and air on the human external breathing function. The study involved eight subjects aged 24 ± 4 years who breathed the gases heated up to a temperature of 58 ± 5°C and atmospheric air for 21 min. The effects were evaluated according to the parameters of spontaneous pneometry and forced expiration using the Master Screen VIASYS device. The effect of the heated gases (heliox and air) on humans caused a phase-by-phase increase in the values of the external breathing parameters. Apparently, the patency of airways at the level of tracheas and bronchi appeared to increase significantly during breathing heliox compared to air.
